Specification of Letters Patent.

Patented Feb. 15, 1910.

Application led August 24, 1908. Serial No. 450,031.

To all whom it may cof/wem:

lie it known that I, MILADIN BUNYn'r1N, a citizen of I-lungary, residing at Bakersfield, in the county of Kern and State of California, have in vented a new and, useful Tractionllngii'ie, of which the following ,is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

'lhis invention relates to a means for driving the forward trucks of a traction engine, the object of the invention being to provide means to drive the front wheels of the engine as well as the rear wheels.

ln the drawings in which the same nu meral is applied to the same portion throughout, Figure t a side elevation of an engine equipped with the invention, Fig. 2 1sl a front view ol? the engine showing` the front Wheels and the front', driving gear only, and Fig. 3 is a View of the front driving gear with one. of the wheels of the engine broken away to show the gears more elearl v 'l'he numeral 1 is applied to the fronty drive wheels and 2 is applied to the rear wheels. 'lhe engine is Shown at 4l and drives directly to the rear wheels by meansI of theI inclined shaft 5.' 'l`his shaft has a bevel gear in connection with a bevel gear on the rear axle, and near the center ot'. said rear axle there is a gear which is in mesh with the gear t3 on the rear end of a longitudinal shaft- 7, said shaft passing through an open pipe in the water tank tu' and passing to a point near the front axle t). 'lhe shaft T has a gear l() on its t'ront end which meshes with a large bevel gear ll carried by the l'ront, axle and havingl as its renter the center ot' 'lhis king bolt is a large ball seated in a spherical bearing 13 in the center of the axle, the member having said spherieal bearing being the axle for the large bevel gear ll. A collar Il and a collar 1 5 hold the bevel gear li in its propel' plaee in mesh with the gear lt secured to the axle of the front wheels.

ielow the front axle there 1s a stub shaft 1 7 which is secured to the reach of 'the engine, the 'object being to preventthe front axle trom tipping from front to rear and either or both lifting the bevel gear 11 out ot' the teeth of the small gear l0, or breaking either ot the gears. .lt will be not-ed that the center of motion of the small gear on the longitudinal'shat't is bnt slightly below the center of motion ot thc spherical ball on move the front axle throng which the boiler rests, and the point of the conc of the small gearlO is vertically over the front axle, thus makin@ it possible to ii all the angles necessary to its travel over the country without. injury in any way to the driving gears. Havingthus described my invention what 1 claim as new and desire to secure by Letters Patent of the United States is as follows:

l. In a t laction engine, the combination of a boilerI and engine, n. ball king bolt depending from the boiler, a horizontal axle at the front and at the rear, means'to turn the front axle in a horizontal plane, means to drive the rear axle direct from the engine, a gear carried by the rear axle and in mesh with a gear on a shaft extending longitndi nally of 'the engine under the boiler thereof, a gear at the front. end of said shaft, a hori zontal gear carried above front axle and lying substantiall in the plane of the center of the ball of t ie king bolt and surround-- .ing the same, 'a gearl secured to the front axle and in mesh with the .horizontal gear, and means to prevent the horizontal gear from getting ont of mesh with the gear on ythe longitudinal shaft.

2. ln a traetion engine, the combination of a. boiler, an engine, a ball king bolt depend` ing from the boiler, a horizontal axle at the front and the rear of the boiler, means to drive the rear axle from the engine, a longitudinal shaft having a gear wheel at its front and rear, a "ear carried by the front axle, a snbstantialiy horizontal gear carried above the front axle, and having its axis in the axis of the ball king bolt, and surrounding said hall, said gear in mesh with the gear on said axle, and with one of the gearson the longitudinal shaft, means to prevent. the horizontal gear from getting out of mesh with the gear on the Afront end of the longitudinal shaftnneans to drive said longitudinal shaft and means to move the front axle in'a. horizontal plane whereb the engine may be steered over a road, Substantially as set forth. I

In testimony'whereof I have Set my hand this.17 day of August A. 1).1908, `in the presence ot .the two subscribed witnesses.
